Affinity Tool questions to improve performance

[EtherealN]

NismoRR, AlphaInfinity wasn't talking about affinity.

 

Don't test with affinity on and off, what you want to test is:

 

#1: Affinity off, HT on.

#2: Affinity on 2 cores (4 logical), HT on.

#3: Affinity on 2 cores, HT off.

#4: Affinity on 4 cores (8 logical), HT on.

#5: Affinity on 4 cores, HT off.

 

Reason for 2 and 4 cores is that I saw some really interesting results from our friend over in Vladivostok (so sorry man, I just can't for the life of me recall your name at 4:30am) where there was no difference or even a very small (within error margins) degradation of performance when involving more than two cores.

 

Also, you want to be really certain that you are not giving HT being off credit for gains you made from the affinity.

 

EDIT: Also, be sure to get some average numbers for the FPS from a utility like the benchmark function in FRAPS. Just loading the same map and looking at what you get right at the start is liable to not be very representative.

I see that now, my bad. I'll do further testing this week as you suggest concerning HT, but the results I'm getting are wonderful. Not just at the start, but flying over the city is much smoother, once out of this city I'm in the 50's mostly bouncing off of 60 fps with vsync enabled. That's with "high visibilty" on now. (I mentioned far terrain earlier, that's what they call it in iRacing - oops)

[EtherealN]

Do you have FRAPS?

 

It has a very easy to use benchmarking tool that will give you the data in excel format. With that you can do some awesomely detailed comparisons over time (f.ex, if you run each benchmark through identical track files), or you can just collect some quick and dirty (but still enlightening info) through the min/max/avg function, which just feeds you your lowest FPS, highest and average.

 

Would be real interesting to have some more hard data on the HT thing, so I don't end up talking crap to people. Since I have a Core2 I can't test it myself. :(

[NismoRR]

No Fraps. I might pick it up, but my main interest is to have my system perform well, where I do a bunch of research beforehand, and then play on it. I'm not that technical that I need to analyze FPS data. As far as HT, most people say to leave it off, except for certain applications, not gaming. Runs cooler with it off, etc. In my experience in just two months with this system, HT has made zero difference in Crysis, Empire Total War, or iRacing. I leave it off. But I will check out any affects on affinity later in the week.

[EtherealN]

Yeah, I mean, don't go to trouble on my behalf. I'm just curious since there are conflicting reports and I can't test it myself.

Does this tool work with amd dual/quad core? I remember reading about it in another thread, was tested on intel only. Im hoping to pick up the game today.

 

specs:

asus a8n32 sli deluxe

amd x2 4200

4gb ddr

bfg 8800 gts oc 640mb

bfg physx

x-fi extrememusic

vista home premium 64bit

If it doesn"t, you could try Prifinitty (freeware). I have been using that. You just have to alt-tab out of the loading screens tomake sure the core assignments stuck. There is nothing in the online documentation about limiting it to intel CPUs so you can give it a try.

That's OK :lookaround:

This is only true on certain motherboards. This does not seem to be true on ASUS boards. I have tried this with mine and there is 0 performance degredation when using hyperthreading on an i7 processor.

 

Also no preformance degredation on the GIGABYTE EX58-UD3R with hyperthreading switched on

I have the same board but a Version "2"

 

I get 40 % better FPS with hyperthreading off .

What kind of performance can I expect with my setup? Gonna try DCS Max tool as well. I plan on getting track IR 4 bundle, game comes with a coupon? And eventually a x52 setup, using a logitech force 3d.

difficult to say , i had a similiar set up with an amd x 2 4800 and used to get about 20-30 FPS using Windows Vista Ultimate 32bit and DCS Max.

 

If you haven't got one buy the stick first!
